INK-WELL.

SPECIFICATION forming part of Letters Patent No. 640,630, dated January2, 1900.

Application filed January 30, 1899. Serial No. 703,856. (No model.)

To all whom it may concern.-

Be it known that we, BARTHOLOMEW W. Connor and WILLIAM E. CONROY,citizens of the United States, residing at Port Huron, in the county ofSt. Clair and State of Michigan, have invented a certain new and usefulImprovement in Ink-Wells, of which the following is a specification,reference being bad to the accompanying drawings.

This invention is an improvement on that style of ink-well invented byBartholomew W. Conroy, one of the present applicants, and patented underNo. 153,809. It is designed to provide an ink-well that will not only becheaper in construction and more convenient in use, but one that willprevent damage from freezing and consequent breakage of the well and thespilling of the ink.

To these ends the invention consists in the peculiar construction,arrangement, and combination of parts hereinafter described and thendefinitely claimed at the end hereof.

In the accompanying drawings, Figure 1 is a vertical central section ofan ink-well constructed according to our improvement represented inposition in a desk. Fig. 2 is a side elevation of the upper section orcover. Fig. 3 is a similar view" of the lower section or ink-chamber.Fig. iis a reversed plan of the cover.

Referring now to the details of the drawings by numerals, 1 is the lowersection or ink-chamber, in which is set a rubber tube 2, cemented into ahole 3 in the center of the chamber. Near the bottom is a flange 4,intended to bear against the bottom of the desktop, (indicated by 5,)and on the bottom is an angular projection 6, intended to engage with awrench, by which the two sections of the ink-well may be screwedtogether. Around the outside of the body of the ink-chamber are inclinedangular grooves 7, in which engage pins 8 on the inside of the uppersection orcover 9 and by which the two sections are securely fastenedtogether in the hole 10 in the desk-top. To prevent the upper sectionturning when the two sections are being screwed together, a feather 11is cast upon the outside of the cover, which enters a notch 12 in thewall of the hole in the desk-top.

The cover has a flange 13, which rests against the desk-top, and in itscenter is a recess 14, in which fits a turning cap 15, preferably heldthere by a screw 16, the head of which enters into the top of the tube 2to prevent ink splashing into said tube.

I-Iolesl7 are formed through the cap and the top of the upper section,so that when the two holes register access may be had to the ink below;but when the cap is turned so as to bring its solid portion over thehole the ink is covered up to prevent undue evaporation and keep out thedust.

Projecting from the bottom of the cap is a pin 18, which enters "acurved slot 19 in the top of the upper section and is so arranged thatwhen the pin touches one end of the slot 19 the holes register, and whenit touches the other end of said slot the lower hole is covered.

It is intended to make the two sections of such proportions that whenscrewed together the flanges will bind on the top and bottom of thedesk-top, and at the same time the top of the ink-chamber willfit'against the under side of the cover, as shown; but in some cases.

we may put a gasket of rubber or other ma= terial between the parts.

On the top is a projection 20, which will be found useful in turning thecap to open or close the opening into the ink-well.

By the construction above set forth we have dispensed with the ink-welland spring shown in the aforesaid patent, thereby simplifying andcheapening the construction, and by the use of the internal flexiblerubber tube we provide room for expansion, so that the danger ofbreakage from freezing is avoided, because the tube will yield inwardly,and thus occupy less space as the freezing ink expands.

\Vhat we claim as new is-- 1. The combination in a two-part ink-well, ofan ink-chamber having a flange near its bottom, a cover having acylinder depending therefrom and inclosing the ink-chamber and providedwith a flange, one of said parts hav ing inclined grooves and the otherpart, pins engaging in said grooves, the top of'the inkchamber and theunder side of the cover substantially meeting each other, and a cappivotally secured in the center of said cover and having an apertureregistering when in one position with an aperture in the cover,substantially as described.

2. The combination in a two-part ink-well, of the ink-chamber 1, havingflange 4 and inclined angular grooves 7, with the cover 9, having acylinder depending therefrom and pins 8 engaging in said grooves 'i',the top of the ink-chamber and the under side of the cover substantiallymeeting each other, and a cap 15 pivotaliy secured in a recess 1e in thecover, and having a pin 18 working in a slot 19 in said cover, both thecover and cap having apertures 17 adapted to register to allow access tothe ink-chamber, all substantially as described and shown.

The combination in an ink-well,oa flexi-
